ABSTRACT:
An apparatus for distilling corrosive compounds under high temperatures, which would include primary vessel chamber, having a first interior annular wall lined with a loose polymer, such as PTFE (or TEFLON), a second annular wall exterior to the first annular wall, and defining an annular space between the interior and the exterior wall; a somewhat rigid porous material for supporting the interior PTFE liner positioned along the interior wall of the vessel; device for drawing air out of the annular space between interior and exterior walls, for creating a vacuum at the annular space, so that the PTFE liner is supported firmly against the somewhat rigid porous support member; next, a second means for drawing air out of the interior of the vessel for creating a vacuum therewithin so that a pressure equilibrium is established between the interior of the vessel and the annular space, and a corrosive material can be heated in the vessel chamber under the vacuum, and the liner be maintained flush against the wall of the vessel.
